== Discovery Plugins
Discovery plugins extend Elasticsearch by adding new discovery mechanisms that
can be used instead of {ref}/modules-discovery-zen.html[Zen Discovery].
[float]
==== Core discovery plugins
The core discovery plugins are:
<<cloud-aws,AWS Cloud>>::
The Amazon Web Service (AWS) Cloud plugin uses the
https://github.com/aws/aws-sdk-java[AWS API] for unicast discovery, and adds
support for using S3 as a repository for
{ref}/modules-snapshots.html[Snapshot/Restore].
<<cloud-azure,Azure Cloud>>::
The Azure Cloud plugin uses the Azure API for unicast discovery, and adds
support for using Azure as a repository for
{ref}/modules-snapshots.html[Snapshot/Restore].
<<cloud-gce,GCE Cloud>>::
The Google Compute Engine Cloud plugin uses the GCE API for unicast discovery.
<<discovery-multicast,Multicast>>::
The multicast plugin sends multicast messages to discover other nodes in the cluster.
